US President Donald Trump told reporters earlier on Monday that Washington had sent a group of "very talented people" to collect the facts in Turkey about death of Khashoggi, adding that the team would be returning later on Monday or on Tuesday.
Meanwhile, senior White House adviser Jared Kushner said in an interview on Monday that the US was still collecting the facts in the controversial killing of the Washington Post columnist.
Khashoggi, who has been working for The Washington Post newspaper and was known for his criticisms of Saudi authorities, went missing in Istanbul on October 2 after he entered the Saudi consulate and never came out. The incident caused a significant public outcry in Turkey as well as many Western countries.
US companies and officials have been withdrawing from projects and events related to Riyadh in the wake of the disappearance of the Saudi journalist and emerging claims that the Saudi government was complicit in his murder.
Turkish President Recep Tayyip Erdogan said Sunday that he would deliver a statement on the death of Saudi journalist Jamal Khashoggi at a meeting of the ruling Justice and Development Party (AKP) on Tuesday.
